TropiTrade does not offer eSIM plans for Guernsey that include a phone number or SMS capability. Travelers can only obtain data‑only eSIMs from TropiTrade for this destination. As a result, voice calls and text messages must be carried out through data‑based VoIP applications such as WhatsApp, Telegram, or iMessage. Some destinations may restrict access to certain VoIP services, so users should verify that the apps they rely on are functional in Guernsey before purchasing.
